Um...You're Not At The Beach

I'm in line at my neighborhood Ralph's (grocery store) right now, which is located about 2.5 miles from the beach - much farther than most people are willing to walk. The girl in line in front of me - probably in her mid-twenties - has on a bikini and flip-flops. No shorts. No towel. Just a bikini. In a grocery store. I would snap a picture, but that just seems dirty and weird. Is this normal? Does the fact that we are somewhat close to the beach make this attire NOT so bizarre?
